Pro Gainer – High Protein Gainer from Optimum Nutrition
Pro Gainer is Optimum Nutrition’s flagship gainer. It is much better than Serious Mass. Where Serious Mass has only 15% protein, Pro Gainer has 36% protein. However, it too contains the two artificial sweeteners sucralose and acesulfame potassium.
What the label doesn’t tell you, and it is with almost all American protein powders, is that they might contain rBGH (or rBST). rBGH is a hormone that dairy farmers inject into the cows for added milk production. Europe Union, Canada, Australia and New Zealand ban this hormone. The US did not ban it. We’re not saying that all American milk products contain rBGH. Ben & Jerry ice cream for example refuse to use milk with rBGH. Unless it is specifically stated on the product label otherwise, you should assume all American protein powders to contain rBGH.
If you would like to avoid rBGH, sucralose and acesulfame potassium, you can choose White Knight Anabolic Mass.
